| 20100113711 | CONTROL OF POLYMER SURFACE MOLECULAR ARCHITECTURE VIA AMPHIPATHIC ENDGROUPS - Polymers whose surfaces are modified by endgroups that include amphipathic surface-modifying moieties. An amphipathic endgroup of a polymer molecule is an endgroup that contains at least two moieties of significantly differing composition, such that the amphipathic endgroup spontaneously rearranges its positioning in a polymer body to position the moiety on the surface of the body, depending upon the composition of the medium with which the body is in contact, when that re-positioning causes a reduction in interfacial energy. An example of an amphipathic surface-modifying endgroup is one that has both a hydrophobic moiety and a hydrophilic moiety in a single endgroup. For instance, a hydrophilic poly(ethylene oxide) terminated with a hydrophilic hydroxyl group is not surface active in air when the surface-modifying endgroup is bonded to a more hydrophobic base polymer. If the hydroxyl group on the oligomeric poly(ethylene oxide) is replaced by a hydrophobic methoxy ether terminus, the poly(ethylene oxide) becomes surface active in air, and allows the poly(ethylene oxide) groups to crystallize in the air-facing surface. In this example, immersion in water destroys the crystallinity as the poly(ethylene oxide) sorbs water and the hydrophobic methoxy group retreats below the surface of the polymer. Also disclosed are methods and articles of manufacture that make use of these polymers. | 05-06-2010 |
